Subject: [PATCH] fix USB audio support

fw/b changes in Oreo cause some USB audio devices
which were previously recognized as AUDIO_DEVICE_OUT_USB_DEVICE
or AUDIO_DEVICE_OUT_USB_ACCESSORY now to be recognized as
AUDIO_DEVICE_OUT_USB_HEADSET (0x4000000), causing this error:

AudioPolicyManagerCustom: setDeviceConnectionState() could not find HW module for device 04000000
